AI Technical Summary

Technical Problem

Existing rapid changeover robotic arms are highly dependent on air pressure. When power is lost, the tool side may detach from the robot side, causing the laptop casing to fall off, resulting in production interruptions and increased maintenance costs.

Method used

The mechanical locking structure utilizes a spring to push the second locking head into the gap of the first locking head to complete the locking process. When unlocking, the locking head is retracted by pushing the adjusting ring, completely eliminating the dependence on air pressure and achieving stable connection and rapid separation of the robotic arm.

Benefits of technology

Even in the event of a power outage, the robotic arm can maintain a stable connection, preventing the laptop casing from falling off, simplifying the operation process, improving production efficiency, and reducing maintenance time and difficulty.
